摘要：

用聚硅硫酸铝处理长江水进行生产性应用研究,研究结果表明:与硫酸铝相比,聚硅硫酸铝可降低混凝剂投加量20%-30%;在混凝剂投加量相近时,浊度平均值降低20%-50%;可以增大澄清池处理量15%;投加聚硅硫酸铝,滤池的主要运行参数及效能没有受到不利的影响。

Abstract:

The full- scale application of aluminium sulphate polysilicate to Yangtze raw water treatment is presented. The results show that comparison with aluminium sulphate,the dosage of coagulant decreases 20% - 30%. When the two dosages are almost the same,the average turbidity decreases 20% - 50%. This method can increase 15% of the quantity of the clarified water. Adding aluminum sulphate polysilicate does not have any negative influence on the main running parameters and efficiencies of the filter.

Key words: aluminium sulphate polysilicate, full-scale application, filter
